We study whether fund families efficiently allocate their fund managers to different market segments. Whether a fund manager can generate alpha simultaneously depends on her skills, and on the efficiency of the market segment in which she is employed. We show that in the more efficient...

We show that fund families allocate their fund managers to different market segments such that their skill is rewarded best. Whether a fund manager's skill is rewarded by higher alpha depends on the efficiency of the market segment in which she works. Even skilled managers can generate alpha...

We develop a reduced-form model that allows us to decompose bond spreads and CDS premiainto a pure credit risk component, a pure liquidity component, and a component measuring therelation between credit risk and liquidity. CDS liquidity has important consequences for the bondcredit risk and...

We explore the relationship between CDS premia and bond asset swap spreads on the samereference entity. As Duffie (1999) shows, there is a clear theoretical link between CDS premiaand bond prices if the two quantities are viewed as a pure measure of credit risk. However,many studies provide...

This paper provides the first empirical test of the diversification of opinions theory and the groupshift theory using real business data. Our data set covers management teams and single managersof US equity mutual funds. Our results reject the group shift theory and support thediversification...

In this paper we develop the rst estimator of the covariance matrix that relies solely onforward-looking information. This estimator only uses price information from a cross-sectionof plain-vanilla options. In an out-of-sample study for US blue-chip stocks we show that aminimum-variance strategy...

Using 13F position valuations, we show that hedge fund advisors intentionallymismark their stock positions. We document manipulation even after eliminatingissues inherent in the pricing of illiquid securities. The documented mismarking isrelated to hedge fund incentives. Mismarking is more...

This paper serves two purposes. First, we introduce a new data set on the German stock marketwhich is publicly available to all researchers. It comprises factor returns (a market factor, asize factor, a book-to-market factor, and a momentum factor) as well as returns of portfolioswhich are...
